Most of the time iPhone owners forget there's a SIM card inside their devices. But when it becomes necessary to switch SIM cards, such as while traveling, Apple has made it simple to access. Older devices, namely the original iPhone, iPhone 3G and iPhone 3GS have SIM cards located on the top. Every other iPhone's SIM card is placed on the right hand side of the device.

The A11 Bionic 64-bit chip features an ARMv8-A six-core processor that significantly outperforms the previous generation A10, and is faster than the A10X Fusion found in the iPad Pro.

Most of the rumors and leaks these days surround the 10th-anniversary iPhone 8 coming this fall.

Some rumors were floated that the iPhone SE would be updated this summer, however this has not come to fruition. Now it seems Apple has plans to upgrade internal components on the SE sometime next year.
